RADIATOR ARRANGEMENT FOR AERIAL VESSELS.

Application filed. September 28, 1920. Serial No. 413,443.

To all whom it may concern.-

Be it known that I. KARL Fmnpmcrt Kxrrics, a citizen of the German Republic, and resident of Mannheim. Germany, have invented a certain new and useful Radiator Arrangement for Aerial Vessels, of which the following is a specification.

The cooling-effect of radiators employed for re-cooling the cooling-water of the motors of airships and flying-machines is advantageously regulated by letting the radiator more or less project out of the car. Supporting and guiding the radiator is effected by means of special frames which are attached t0 the outer surface of the car and which. if the car is flexibly suspended, are hinged to it so that in the case of hard landing. that is to say, if the car contacts with the ground, the radiator-frame cannot get between the car and the ship-body and imperil this latter. Conducting the hot water to the radiator and the cooled water away from it can be effected, with arrangements of the before-mentioned kind and in a manner guaranteeing reliability of service. only by means of hoses of a length appropriate to the extent of the movement of the radiator. But as this latter is located above the motor, the water-connections in question require much s. ace. If the radiator is in its deepest position within the car, no steamor air-spaces must arise at the highest parts of said connections in inclined positions of the air-ship because then the proper circulation of the cooling-water would be inter-- rupted. This demand restricts and renders difficult the adaptability of radiator-arrangements of the kind in question.

The before-mentioned drawbacks are overcome by my invention which consists in the facts, that. first, the radiator-frame which is arranged at the car-hood is firmly cbnnected with the radiator; second. both the radiator and its frame can be lowered down into the'interior of the car, and third, the radiator is guided in its vertical motion by tubes which at the same time are employed for conducting the hot water to the radiator and the cooled water away from it, as is all more fully described hereinafter.

In order to make my invention more clear, I refer to the accompanying drawings, in which- Figure 1 is a vertical cross-section through the car f an airship provided with an arrangement according to my invention; Figure 2 is a vertical longitudinal section through the. same car. of which one end is broken away. and Figure 3 is a representation similar to Figure l. the car. however. being left away and the parts shown representing a modified form of execution.

In the form of construction shown in Figures 1 and the radiator a. is firmly connected with the frame I) and guided at the points 0 and (Z of the cz'ir-hood. Fun ther means for holding and guiding the ra diator are provided in the interior of the car and consists of two pipes and (Figure l) which support the radiator. and of the vertically upwards extending ends of two pipes /u and I (Figure 2) which guide the pipes e and f. K and it (Figure 1) are stultlng boxes provided at the ends of the pipes Z and 7. The pipes 7.: and (i serve for leading the water to be cooled to the radiator. and the pipes f and 7 serve for leading the cooled water away from the radiator. or revcrsely. and the pipes e and f with the radiator may be vertically displaced. i. e.. adjusted. in the pipes Z- and 7 with their smiling-boxes 1 and 71. The pipes e and 7' form parts of the radiator-supporting frame and these frameparts are. thus. moved up or down together with the radiator itself. The air-resistance during a voyage is thus reduced to a inini mum, there being no radiator frame-parts projectingoverthecar-hood. and as no means for turning the radiator-frame up or down are necessary in the novel form of construction before-described. the weight is considerably reduced and the whole is greatly simplitied.

()wing to the arrangement that parts of the supporting frame of the radiator are made use of for supplying the water to this latter and conduct it away from it. and that those parts. i. e.. the tubes 0 and are. as such. rigid parts which are vertically displaceable in rigid parts. i. e.. in the ends of the pipesla and 7.110 flexible tubes. or no hoses respectively. need be employed. The whole can be more easily SllI'\'t \'t(l and is better accessible. Finally. as the cooling-water pipes lie below the platform of the car. there is no danger of the water-circulation failing or of steam'or air collecting in them.

In the form of construction shown in Figure 3, there are (o-axial tubes m and n, of which the one serves for conducting the hot water to the radiator and the other for leading the cooled water away from it. In this instance only one stutfing-box is required. The saving in space is in this case still greater than in the III'St-(ICSCIIbHl example.

The same combination and arrangement of parts may be employed also for the cars or hulls of big flying-machines.

Having now described my invention what I desire to secure by a patent of the United States is: V 1. In an aerial vehicle, the combination with a vertically movable radiator for recoolin; the hot cooling water of the motor, of telescopically arrai'lged pipes located below the radiator: the movable parts-of said pipes being connected with the said radiator and the stationary parts of the said pipes being connected with the connecting-pipes between the radiator and the motor-cylinder, for the purpose set forth.

2. In an aerial vehicle, the combination with a vertically movable radiator for recooling the hot cooling water of the motor, of two telescopically arranged pipes ar ranged below the radiator, the movable inner pipes being connected with the radiator and bein; adapted the one for supplying the hot water to the radiator, the other for leading the cooled water out of it, and the outer parts being connected with the connta-ting-pipes between the radiator and the motor-cylinder. for the purpose set forth.

3. In an aerial vehicle. the combination, with a. vertically movableradiator for recooling the hot cooling water of the motor of telescopically arranged pipes located below the radiator; the movable parts of said pipes being connected with the said radiator and the stationary parts of the said pipes being connected with the connecting}pipes between the radiator and the motor-cylinder, stationary radiator guide-parts attached to the car-hood, and movableguide-parts attached tothe radiator. substantially and for the purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.
